My invention relates to improvements book or luggage straps and is inthe nature of" an improvementon the book strap d1s= closed mycopendingapplicatio'n Seria No. 93,014, filed March 8, 1926.' I

The object of myinvention is to improve the construction of book strapsof this-nature and torender the same more eflicient in operation. V

Y A-mor'e specific object isto provide an endless book strap' that iseasily placed aroundbook's or similar objects and'tight-' ened thereonand'that has a buckle 'oriastener within-the loop portion of said; strapwhich buckle is adapted to" hold the strap from working loose on .thebooks, said buckle being, quickly and" easily releasable manually.

Other and more specific objects will be apparent from the followingdescription taken in connection With the accompanying drawings, whereinFigure 1 is a perspective view of va book strap constructed inaccordance with my invention as it may appear when in use;

Fig. 2 is a perspective view showing the strap removed from the books;

Fig. 3 is an end elevation of the same showing the strap tightenedaround books; and

Fig. 4 is a sectional view on a larger scale of the buckle used inconnection With my book strap.

Referring to the drawings, throughout which like reference numeralsindicate like parts, 5 designates a'single one'piece strap that ispassed slidably through one end 6 of a buckle 7 and that has its twoends, as at 8, fixedly secured, as by rivet 9, to the other end 10 ofthe buckle 7 so that said strap forms in effect a loop of doublethickness fixedly connected with one end of the buckle and slidablyconnected with the other end of the buckle. The loop tormed by the strapis double thickness, one part being on the inside of the loop. Both ofsaid parts pass slidably through a keeper 11.

The end Got the buckle 7 is made with an inclined surface as shown inFig. 4 and said buckle has a flat tongue 12 mounted on a pivot 13 andprovided with a relatively broad edge 14 that is adapted to cooperatewith the inclined buckle end 6 in gripping the strap. The edge 14 issharp enough to securely grip the strap by awedging action but is-notsharp enough tocut the strap,-

Saidedge- 1 1;v is preferably notched to causeto gripthe strap moreqfirmly. A com-' pressioii spring-.15, urges theton'gue 12 intoengagementwitlrthe strap/5 and said tongue maybe. moved to disengage orrelease the strap exerting apressure on a. thumb -piece 16' on the''t'ongue. From the preceding description itEwiH be seen that the loopportion of the strap may be'rreadily drawn buckle in one direction butcan not-be "drawn through the buckle in the'opposite.directionunlessthetongue 12 is maniiall'y'ra'is'ed lor' released. 7 7 3 i 1 Inplacingthe strap on books 17 the strap is o ened-tilt as sliown in ,2and -tlie banks inserted-within the loop and a u is exerted on' tli'eouteiptrfioao'f the strap between the keeper 11 and the end 6 of thebuckle thereby pulling the strap through the end of the buckletightening the same around the books and drawing out the portion onwhich the pull is exerted to form, a hand hold or loop 18 for engagementby the hand or arm incarrying. In tightening the strap on the books thekeeper 11 and buckle 7 are preferably adjusted so that they aresubstantially opposite to each other and near the top edge of the booksthereby preventing the books from turning over or twisting withinthestrap. When the strap is applied to the books in the manner justdescribed a pull on the hand hold portion 18 will draw the strap throughthe buckle and tighten the same on the books and said buckle will engagewith and hold the strap and prevent the same from loosening. To loosenthe strap on the books a pressure is exerted on the. thumb piece 16thereby raising the tongue 12 and permitting the strap to be drawn backthrough the buckle and loosened.

The strap is exceedingly simple in construction, holds the bookspositively, has no Y loose parts to become lost and is very easily andquickly put onto or removed from books or packages. r

It is also possible to reverse the position of the strap on the booksletting the outer portion of the strap between the keeper 11 and the end10 ofthe-buckle serve as a hand hold but the strap is more dilficult toapply to the books and to remove the books from when used in thismanner. 7

The foregoing description and accompanying drawings clearly disclose apreferred embodiment of my 1nvent1on but it W111 be understood that thisdisclosure is merely illustrative and that such changes in the devicemay be made as are within the scope and spirit of the following claims.

W' hat I claim is I 1. A book strap, embodying a buckle, a strap memberhaving its two ends fixedly connected with one end of said buckle andhaving its medial portion slidable through the other end of said buckle,said strap forming a loop of double thickness, a keeper slidable 011said strap, and a releasable spring pressed tongue in said bucklenormally holding said strap against sliding movement in one directionthrough said buckle.

2. The book strap as described in claim 1 in which those portions ofsaid strap adjacent the fixedly'secured ends are adapted to pass aroundbooks and the inner portion of the strap adjacent the slidableconnection with the buckle is arranged to be drawn across the top edgeof said books and the outer portion of said strap adjacent said slidableconnection with said buckle is arranged to form a handhold loop.

3. A book strap, embodying a buckle, a single strap member having itstwo ends fixedly connected with one end of said buckle, said strap beingdoubled and the medial portion of said strap member being slidablethrough the other end of said buckle, a keeper slidable on the doubledportion of said strap, and manually releasable means in said buckle fornormally permitting sliding movement of said strap through said bucklein one direction and preventing sliding movement of said strap in theopposite direction, said. strap being adapted to be placed around bookswith said buckle near the upper edge of the books on one side and saidkeeper near the upper edge of the books on the other side, the innerportion of said strap being drawn across the top of said books and theouter portion of said Strap being drawn upwardly through 'saidbuckle toform a hand hold said buckle preventing loosening of said book strapuntil said buckle tongue is released.

In Witness whereof, I hereunto subscribe my name this th day ofJanuary'A. D. 1927.
